3.3 Swing Head
730 Sample Changer, Introduction

3.3 Swing HeadSwing Head
To ensure that the individual vessels are approached with preci-
sion even when using multiple-row sample racks, a 759 swing
head can be installed instead of the normal titration head. The
swing head is fitted with either a titration head (2.759.0020) or a
transfer head (2.759.0010) for pipetting the sample from the sam-
ple vessel into a bigger titrating vessel.
3.3.1 Prerequisites
If a swing head is to be used, program version 730.0013 or higher
needs to be installed on the sample changer. The 759 swing head
can be used in combination with the following racks:
Sample rack 759 model Number of
towers
Titration 48 x 75 mL for direct titration
Article No. 6.2041.350
Article No.
2.759.0020
1, 2
Pipetting 126 x 15 mL and
2 x 150 mL for pipetting
Article No. 6.2041.400
Article No.
2.759.0010
2
If the two-row sample rack with 48 beakers is used on the 2-tower
model for direct titration, sample beakers cannot be approached
with tower 2. If the rack is used for transferring samples from 126
test tubes into two central measuring/rinsing vessels (special
beakers), all the positions can be approached with tower 1,
whereas tower 2 can only approach the two special beakers.
The swing head cannot be used in combination with other stan-
dard rack types.
3.3.2 Installing the Swing Head
The best procedure for installing the swing head is described be-
low. The swing head will normally be installed by our service per-
sonnel.
If a 2-tower sample changer is used, the swing head must al-
ways be connected to tower 1 (see page 6)!
With 2-tower sample changers, tower 1 is first moved into a cen-
tral lift position and tower 2 is moved into the rest position.
Turn off mains power switch.
Install the new titration head (6.1462.020) or transfer head
(6.1462.010) on the underside of the swing head.
